(1) In order to ensure the safety distance and safety margin of construction operations of the cross-frame frame and cable, the construction teams shall strictly follow the “No-stop power-off construction measures” for construction preparation and construction.
(2) Before the construction of the uninterrupted power line, the application shall be submitted to the operation department in writing to “exit the automatic reclosing”, and the “three measures” plan shall be submitted to the relevant department of the power supply bureau for approval before the construction can be carried out without power failure.
(3) During the construction process of the uninterrupted power line, the operating department that is crossing the power line must be invited to conduct on-site monitoring. The construction team must have a security guardian.
(4) Personnel participating in the construction shall be familiar with the method of use, scope of use and rated load of the tools, and shall not use unqualified tools.
(5) When working near the electrified body, the insulated rope should be used to transfer the objects up and down. The whole process should be monitored by special personnel.
(6) The construction of the line across the uninterrupted line shall be carried out under good weather. When lightning, rain, fog, strong wind and relative humidity are large, the work shall be stopped and the insulation net shall be protected to prevent the insulation net from being damp and affected. wet. If the above conditions are encountered in the construction, the nets and ropes that have been laid out should be protected to avoid accidents.
(7) Cross-frame, pull wire, small pole and ground anchor, grounding, and must be carefully checked before use.
(8) After the frame is assembled, the safety distance between the upper wire and the wire should be ensured.
(9) After the frame body is assembled, the frame body should be temporarily grounded in time.
(10) During the assembly and dismantling of the frame, the frame, cable, small pole and live line should always maintain a safe distance.
(11) Insulation nets should be inspected for wear before use, and it is strictly forbidden to use them. Before use, it should be dried or dried, and the insulation degree should be checked. The insulation resistance is not less than 700 megohms.
(12) Pulling the insulated guide rope and laying the insulated mesh rope shall not yank the mammoth.
(13) Grounding protection measures shall be taken for the take-up pulleys at both ends of the crossing.
(14) When installing the accessory, a rubberized steel rope sleeve shall be installed on both sides of the spanning gear as the second line protection measure to prevent the wire from falling.
(15) After the completion of the construction, the capping net (rope) and the cross-frame frame body should be removed as soon as possible after the entire wear-resistant section attachment. A safety guardian should be provided when dismantling.
